25c51279cf Revert "[#1442] Make sure closing the channel will not cause an UnsupportedOperationException"
This reverts commit a1a86b9de4 because the
semantic of ctx.isRemoved() is confusing to a user - why is
ctx.isRemoved() false when handlerRemoved() is invoked? A better
solution would be check if the connection is inactive and mark the
promise as failure before attempting to write anything.

e9c6406819 Remove the AIO transport as NIO is just faster
The AIO transport was added in the past as we hoped it would have better latency as the NIO transport. But in reality this was never the case.
So there is no reason to use the AIO transport at all. It just put more burden on us as we need to also support it and fix bugs.
Because of this we dedicided to remove it for now. It will stay in the master_with_aio_transport branch so we can pick it up later again if it is ever needed.

14158070bf Revamp the core API to reduce memory footprint and consumption
The API changes made so far turned out to increase the memory footprint
and consumption while our intention was actually decreasing them.

Memory consumption issue:

When there are many connections which does not exchange data frequently,
the old Netty 4 API spent a lot more memory than 3 because it always
allocates per-handler buffer for each connection unless otherwise
explicitly stated by a user.  In a usual real world load, a client
doesn't always send requests without pausing, so the idea of having a
buffer whose life cycle if bound to the life cycle of a connection
didn't work as expected.

Memory footprint issue:

The old Netty 4 API decreased overall memory footprint by a great deal
in many cases.  It was mainly because the old Netty 4 API did not
allocate a new buffer and event object for each read.  Instead, it
created a new buffer for each handler in a pipeline.  This works pretty
well as long as the number of handlers in a pipeline is only a few.
However, for a highly modular application with many handlers which
handles connections which lasts for relatively short period, it actually
makes the memory footprint issue much worse.

Changes:

All in all, this is about retaining all the good changes we made in 4 so
far such as better thread model and going back to the way how we dealt
with message events in 3.

To fix the memory consumption/footprint issue mentioned above, we made a
hard decision to break the backward compatibility again with the
following changes:

- Remove MessageBuf
- Merge Buf into ByteBuf
- Merge ChannelInboundByte/MessageHandler and ChannelStateHandler into ChannelInboundHandler
  - Similar changes were made to the adapter classes
- Merge ChannelOutboundByte/MessageHandler and ChannelOperationHandler into ChannelOutboundHandler
  - Similar changes were made to the adapter classes
- Introduce MessageList which is similar to `MessageEvent` in Netty 3
- Replace inboundBufferUpdated(ctx) with messageReceived(ctx, MessageList)
- Replace flush(ctx, promise) with write(ctx, MessageList, promise)
- Remove ByteToByteEncoder/Decoder/Codec
  - Replaced by MessageToByteEncoder<ByteBuf>, ByteToMessageDecoder<ByteBuf>, and ByteMessageCodec<ByteBuf>
- Merge EmbeddedByteChannel and EmbeddedMessageChannel into EmbeddedChannel
- Add SimpleChannelInboundHandler which is sometimes more useful than
  ChannelInboundHandlerAdapter
- Bring back Channel.isWritable() from Netty 3
- Add ChannelInboundHandler.channelWritabilityChanges() event
- Add RecvByteBufAllocator configuration property
  - Similar to ReceiveBufferSizePredictor in Netty 3
  - Some existing configuration properties such as
    DatagramChannelConfig.receivePacketSize is gone now.
- Remove suspend/resumeIntermediaryDeallocation() in ByteBuf

This change would have been impossible without @normanmaurer's help. He
fixed, ported, and improved many parts of the changes.

23d0178494 Introduce EventExecutor.shutdownGracefully() that deprecates shutdown()
shutdownGracefully() provides two optional parameters that give more
control over when an executor has to be shut down.

- Related issue: #1307
- Add shutdownGracefully(..) and isShuttingDown()
- Deprecate shutdown() / shutdownNow()
- Replace lastAccessTime with lastExecutionTime and update it after task
  execution for accurate quiet period check
  - runAllTasks() and runShutdownTasks() update it automatically.
  - Add updateLastExecutionTime() so that subclasses can update it
- Add a constructor parameter that tells not to add an unncessary wakeup
  task in execute() if addTask() wakes up the executor thread
  automatically.  Previously, execute() always called wakeup() after
  addTask(), which often caused an extra dummy task in the task queue.
- Use shutdownGracefully() wherever possible / Deprecation javadoc
- Reduce the running time of SingleThreadEventLoopTest from 40s to 15s

    - Returns null on interruption or wakeup
  - Make sure runShutdownTasks() return true even if an exception was
    raised while running the shutdown tasks
  - Remove unnecessary isShutdown() checks
  - Consistent use of SingleThreadEventExecutor.nanoTime()

Replace isWakeupOverridden with a constructor parameter

7884574c7b Remove freeInboundBuffer() and freeOutboundBuffer() which has no value
- Fixes #1308

freeInboundBuffer() and freeOutboundBuffer() were introduced in the early days of the new API when we did not have reference counting mechanism in the buffer. A user did not want Netty to free the handler buffers had to override these methods.

However, now that we have reference counting mechanism built into the buffer, a user who wants to retain the buffers beyond handler's life cycle can simply return the buffer whose reference count is greater than 1 in newInbound/OutboundBuffer().

4a792151b0 Rewrite bridge implementation in DefaultChannelHandlerContext
This commit splits bridge into two parts.  One is NextBridgeFeeder,
which provides ByteBuf and MessageBuf that are local to the context
whose next*Buffer() has been invoked on.  The other is a thread-safe
queue that stores the data fed by NextBridgeFeeder.feed().

By splitting the bridge into the two parts, the data pushed by a handler
is not lost anymore when the next handler who provided the next buffer
is removed from the pipeline.

af4b71a00e Remove special handling of Object[] in codec framework (a.k.a unfolding)
- Fixes #1229
- Primarily written by @normanmaurer and revised by @trustin

This commit removes the notion of unfolding from the codec framework
completely.  Unfolding was introduced in Netty 3.x to work around the
shortcoming of the codec framework where encode() and decode() did not
allow generating multiple messages.

Such a shortcoming can be fixed by changing the signature of encode()
and decode() instead of introducing an obscure workaround like
unfolding.  Therefore, we changed the signature of them in 4.0.

The change is simple, but backward-incompatible.  encode() and decode()
do not return anything.  Instead, the codec framework will pass a
MessageBuf<Object> so encode() and decode() can add the generated
messages into the MessageBuf.
